• yes sorry my link was a dupe. My original old zoomer is here:

• yes Paulo, PS3 mandel is really computing 1920*1080 pixels, which is really impressive, and don'"t use "zoom" trick.
  My version use a nice trick wich could be used to otimize the ps3 version, but the algortihm should be a bit harder to run on SPU with good load balancing. Basically the idea is that if you can find an area of the mandel where the perimeter is made of the same pixel, then all the enclosed area can be filled with that pixel value. This is a "huge" optimisation, but tricky to do on SPU

• Just for fun, I just added an old 4kb "deep" Mandel Zoom I made some years ago. You can get it here:

  As Zerkman say the zoom depth is limited with single precision float. I use double, wich is quite slow on CELL/SPU.

• I love mandelbrot and PS3 so it rocks :-)
  Btw, could you tell us a bit more about what toolchain did you use to build such PS3 demos? Any url available?

• tiny mode is a classic LZ stuff. I mean the "large" depacker (the one with two MUL instructions). Did the 68000 version come from a small C version?
  I'm interested by the small C version.

• Hi, me again :-) The package include the 68000 source code of LZMA depacking routine. The routine is really small compared to the original C version of the official LZMA SDK. So my question:
  Is that depacker the same version as the latest LZMA sdk? And if yes, could you point me to the "small" C version? Did you get it somewhere, or did you extract it from original source code?
  thanks!

• you got it! thanks, it works now like a charm. LZMA is really amazing. My latest ATARI sound demo disk is now about 700Kb instead of 820kb!!! The drawback is that depacking is really, really slow (but you have to pay to get such packing ratio :-))

• thanks! it's almost perfect :-) Why -t is "if possible" ? I want to try to pack my complete demo directory structure (LZMA seems a bit slow) with tiny mode, and some files append to be 0 bytes! could you change that if you specify -t, it output a tiny model file, even if -l would have produce smaller result?
  
  (btw: my program crash with some files when trying to use large model. In the depacker you specifiy A2 should point on probs, is it only a 15980bytes buffer large? or is there something else to worry about?)
